WINDOW FRAMING. i

` Appucanon ined october 19, 1925. senai No. 63,210,

My invention relates to window framing adapted especially for use in connection with basements, cellars, garages, shops and the like, and the paramount object of my inl vention is the provision of an improved window training` which will `embody certain desired features of simplicity, elticiency and convenience, and which will be economical in manufacture. l .4. 1 Y

Other objects will appear hereinafter. j The invention consists in the combinations and arrangements of parts hereinafter described and claimed. i

The invention will be best` understood by 15 reference to the accompanying" drawings forming a part of this specificatiomand in which, j

Fig. 1 represents a front elevational view of a` structure embodying my invention;

Fig. 2 is a cross section taken on the line 2-2 of Fig. 5 and showing the cam action latch and thebearing arm therefor;

Fig. 3 is a detail view of the latch; j Fig. 4. is a fragmental plan and section 25 taken on the line 4.--4 of Fig. 6; .e

Fig. 5 is a fragmental section taken on the line 5`5 of Fig. 6; y

Fig. 6 represents a .vertical section through the window structure, this View being taken substantially on the line 6-6 of Fig. 1; and Fig. 7 represents a `fragmentalperspective and sectional view illustrating in particular how the sash-framing is pivotally supported on the main framing-` The preferred embodiment of my inven tion, as illustrated in the accompanying drawings, comprises a sash holding training composed of a channel framing 8 whose opposed sidcs or flanges 9 and 10 project outwardly all around from the connecting web or cross strip 11, and of an angle framing 12 `whose side or flange 13 is welded or otherwise rigidly secured to the outwardly projectingllange and projects inwardlyall around` from the channel framing as best depicted in Fig. 6. thus produced by welding or otherwise securing together a channel framing and an angle framing so that the sides 9 and 10 of the channel framing project outwardly of the structure and the side 13 of the anglett` `framing projects inwardly of the structure` provides a sort of stepped or z1gzagged structure in cross section, the same having` double seating faces comprising the side 9 The simple structure e and the side 13, which sides are connected"` by the'cross piece or wall like web 11. The groove defined bythe sides 9 and 10, .and as well the angle defined by the side 10 and outwardly projecting flange 14 of the angle framing, are utilized to receive masonry, reenforced concrete or other material by which the window framing may be properly secured within the wall of the building.

` The framing 15 for the windmv sash con` forms in cross sectionto the stepped or Zigzagged arrangement of the main framing composed of the` channel framing 8 and the angle framing 12. To this end, the sash is produced with an outwardly projecting side or. weathering face 16 whichis adapted to have weathering Contact with the` seating face 9, with a cross strip or wall 17 which parallels and supplements the cross strip 11, and with an inwardly extending weathering face 18 whichis adapted to haveweathering Contact with the seating face 13, the sash further being preferably constructed with an outwardly projecting flange 19 which snita bly tits within the inner edge of the inwardly directed seating face 13. By this arran ement, the sash is provided with dou le weathering faces adapted to effect weathering seals with the two seating faces on the main framing.- f

" For the purpose of pivotally supporting `the sash to the main framin the sash, at

its top edge, is provided with outwardly projecting pivot pins 2() adapted to `have bearing in suitable bearing pieces 21 secured tothe seating face 9 of the main framing. The notches 22, which receive the pivot pins 20, have downwardly and rearwardly inclined bottoms 23 which guide the sash to its place within the framing so that the weathering faces 16 and 18 will have weathertight contact with their seating faces 9 and 13 when the sash is forcibly pressed to locking position by a latch 24 pivoted at 25 to ythebott-om side or weathering face of the sash. The latch "24 has a hook end 26 adapted to engage under a keeper 27 Iliade fast with the main framing. Said keeper 27 is made with a projecting bearing arm u28 against which a cam face 29, provided on the latch and hook, engages so as to forcibly` press the sash inwardly of the frame when the latch is manipulated to engage the hook 26` with the keeper.v Under this arrangement, the sash is adapted to be elevated and lowered by swinging it upon the pivot pinsv :ind is further adapted to have weathertight engagement all around with the two seating faces of the main framing when the latch is locked with its keeper.

Vhile I have illustrated and describedthe preferred form of construction for ca rying my rinvention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be'limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what l claim as new andl desire to secure by Letters Patent is:

l. A window construction comprising a main framing having an outwardly projecting flange andan inwardly projecting flange connected by a web part; and a sash framing having an outwardly projecting` flange and an inwardly projecting flange adapted respectively to seat against the corresponding flanges of the main fraining and connected by a web part adapted to be situated opposite the web part first mentioned; alateral flange on the inwardly projecting flange of the sash framing to engage vith the edge of the inwardly projecting flange of the main framing; and means for securing the sash framing in place, substantially as described.

2. A window construction comprising a main framing having an outwardly projecting flange and an inwardly projecting flange connected by a web part; a sash construction composed of four faces `connected in angular. relation and comprising Va face adapted to seat. against said outwardly projecting flange; a face adapted to be situa-ted opposite said web part, a face adapted to seat 2 'Y 1,6e1,19s

against said inwardly projectingy flange; and a face adapted to engage the edge of said inwardly projecting flange, substantially as described.

3. A window construction comprising a main framing composed of a. channel fraining and an angle framing united flange to V- flange with the union flange of the angle framing forming an inwardly projecting seating face and with the free flange of the channel framing forming an outwardly projecting seating face, a sash construction composed of an'angle framing having an ontwardly projecting flange at one edge adapted to seat against the outwardly projecting Seating face of the channel framing and having a. laterally projecting flange at the other edge adapted to engage the edge of the inwardly projecting seating face of the angle framing firstI mentioned; and means for securing the Y sash to said main framing, substantially as described. Y 05 Ll. A window construction comprising a main framing composed of a channel framing and an angle framing unitedflange toflange 'with the union flange of theaugle framing projecting inwardly of the channel framing to form a seating face and with the free flange of the channel framing forming a sea-ting face; a sash constructed with outwardly and inwardly projecting weathering faces adapted receptively to engage the seating face of the channel framing and the seating face of the angle framing; and operative connections between said framing. and sash for forcibly'pressing the sash to position with said weathering faces in weathertight contact with said seating faces, substantially as described. Y

In testimony whereof I have signed my name to this specification.
